Finding foods that prevent disease

A new UC Davis study has found that a diet rich in walnuts will help to lower LDL — or “bad” — cholesterol, prevent bone loss and even fight cancer. 

For the study, researchers led by Paul Davis of the Department of Nutrition fed mice with prostate tumors the human equivalent of three ounces of walnuts a day. At the conclusion of the study, the mice’s tumors shrunk by 50 percent, and tumor growth slowed by 30 percent compared with control mice. 

“Our findings suggest that eating a diet containing walnuts may slow prostate tumor growth,” said Davis.

With new scientific discoveries like this, UC Davis is improving the health and lives of people around the world. Visit the UC Davis Cancer Center to learn why the university is a leader in research and innovative approaches to cancer prevention, diagnosis and treatment.
